#1354 closed defect (fixed)

GPX file fails to upload to OSM, complaining about missing <time> tags

Reported by: Andrew Gee Owned by: dsilvers@…
Priority: major Milestone:
Component: utils Version:
Keywords: gpx upload Cc:


I use Nokia Sportstracker to take traces with my N95 phone. I have been using this method for some time now, successfully uploading traces to the server.

I made a few traces today and wanted to upload these. When I attempted to, it failed and sent me an email saying "Found no good GPX points in the input data. At least 75% of the trackpoints lacked a <time> tag."

I have checked my gpx file and can confirm there are time tags there, and in the correct format.

I have attached one of the gpx files in question.

Looks like the problem with this one is that it has no timezone indication at all (which is valid).

Through attempting to play around with things, I ended up deleting a gpx file, from my profile, that I successfully uploaded the other day. So I just tried to re-upload that trace, which resulted in the same error, indicating this is a recently introduced bug, I would have thought.

I have actually narrowed this down to a problem with the seconds part of the time tag. The application I use for my traces, sportstracker, included milliseconds after the seconds, after a decimal point. These used to be fine in uploading to OSM, but now they're not.

I managed to upload a trace by removing all the milliseconds by hand, from the gpx file.

Is having the milliseconds in the time tag valid, or is this a problem with the sportstracker software I use?

It is valid yes, although a quick reading of the xsd:dateTime specification might lead you to believe otherwise as the main syntax shown does not provide for a fractional second. It references ISO 8601 however, and that does allow for a fractional component. In addition one of the examples in the xsd:dateTime spec does have a fractional component.
